飲水杯彈出式Campus 400毫升 - 熱帶海洋

My kid tested this one by shaking it upside down in the car and not a single drop came out, which is exactly what we needed for school bags. The pop-up spout is simple enough for small hands to manage, and the 400 ml size fits their lunchbox pocket perfectly.

The carrying loop is sturdy enough that my kid can hook it onto their backpack without me worrying it’ll snap. The pop-up lid clicks shut firmly, and after a month of daily school use, not a single drop has leaked in the lunchbox.

It’s been in my son’s backpack for three weeks now, and not a single drop has leaked onto his homework. The carrying loop makes it easy for him to grab on the way out the door, and the 400 ml size fits perfectly in the side pocket.
